I wont be in a position to fix that depending on HDFS-1804 as we are
upgrading to CDH4 in the coming month. Just wanted a short term solution. I
have read somewhere that manual movement of the blocks would help. Could
some one guide me to the exact steps or precautions I should take while
doing
you can write a simple tool to move blocks peer to peer. I had such tool
before, but I cannot find it now.
background: our cluster is not balanced, load balancer is very slow, so i
wrote this tool to move blocks from one node to another node.

Does this require any downtime? I guess it should and any other precautions
that I should take?
Thanks Azuryy.

It don't need any downtime. just like Balancer, but this tool move blocks
peer to peer. you specified source node and destination node. then start.

You can safely move block files between disks. Follow the instructions

Hi,
I am new to the mailing list.
I am using Hadoop 0.20.2 with an append r1056497 version. The question I
have is related to balancing. I have a 5 datanode cluster and each node has
2 disks attached to it. The second disk was added when the first disk was
reaching its capacity.

Thanks Harsh. The jira is fixed in version 2.1.0 whereas I am using Hadoop
0.20.2 (we are in a process of upgrading) is there a workaround for the
short term to balance the disk utilization? The patch in the Jira, if
applied to the version that I am using, will it break anything?
Thanks

Hi,
That probably break something if you apply the patch from 2.x to 0.20.x,
but it depends on.
AFAIK, Balancer had a major refactor in HDFSv2, so you'd better fix it by
yourself based on HDFS-1804.
